Abstract: Edible podded peas viz., snow pea ( Pisum sativum var. saccharatum ) and sugar snap pea ( Pisum sativum var. macrocarpon ) are valued for their tender, parchment-free pods and sweet flavor. In present study, morphologically 26 diverse genotypes were characterized based on pod colour, flower colour, seed colour and pod type. Among these, four morphologically and phenotypically diverse genotypes viz., ‘Royal Snow’, ‘Punjab Mithi Phali-3’, ‘Honey Snap’ and ‘Mithi Phali’ were identified and utilized for developing reciprocal segregating populations between snow and sugar snap peas (Mithi Phali × Honey Snap, Honey Snap × Mithi phali, Royal Snow × Punjab Mithi Phali-3, Punjab Mithi Phali-3 × Royal Snow) to study the maternal/cytoplasmic inheritance. Phenotypically first generation hybrids across all reciprocal crosses indicated dominance of purple flower colour over white, green pod colour over yellow and purple pigmented pods, brown/light brown seeds over green colour seeds and snow-type over sugar snap pods without showing maternal/cytoplasmic inheritance. Segregating F 2 populations followed expected Mendelian inheritance with chi-square (χ 2 ) analysis confirming 3:1 best fit ratio, indicating single dominant gene inheritance for these traits in edible podded peas. These findings provide valuable insights for the genetic improvement of edible podded peas.
